DESCRIPTION
Black silicon carbide is petroleum coke and high quality silica as the main raw material, through the resistance furnace high temperature smelting, smelting into high purity crystal, high hardness.Because it is very hard, high fire resistance, even at high temperature also has chemical stability, so it is suitable for refractory materials, as well as semiconductor crystal fine grinding and cutting processing, precision grinding stone materials, but also the most suitable for cast iron, brass, copper, aluminum, stone, optical glass, etc. In addition, it is also widely used in abrasive coated products such as grinding wheel and sandpaper for finishing.
